Just a thought, maybe making it optional for posts. Gold, Mods, Admins, any other that would be given the privilege, would have the option to make their posts colored. I don't know any of the specifics on what happened with that, or how to make it work, so my bad if it's been suggested elsewhere or not easily achieved.

Well one thing i can do is make non eye-injuring background images for people who earn the thing, this way we would have some sort of consistency since not everyone's good at choosing colors that work with the forum's skin.
